DNA (deoxyribonucleic acid) is the nucleic acid polymer that forms the genetic code for a cell or virus. Most DNA molecules consist of two polymers (double-stranded) of four nucleotides that each ...

Protein synthesis is vital for life, translating genetic information from DNA to functional proteins through transcription ...

There has been some incredible research into the role this DNA plays in modern human neurodevelopment, so here's an overview ...

Northwestern Medicine investigators have discovered a novel mechanism that recognizes and eliminates "bad" transcriptional ...

DNA methylation is the covalent addition of methyl groups to DNA bases, typically the cytosine of CpG dinucleotides. It is catalyzed by methyltransferase enzymes using a S-adenosyl methionine ...

Comparison of that ancient DNA with modern human DNA showed that the two species had interbred and that people today still carry the genetic fingerprint of that intermixing. Since then ...

Of course, though, testing a child's parentage based on physical features is far too subjective — that's typically where DNA tests come in. Such tests can offer a far more scientific way of ...

While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means ...

A 2015 report published by a private genomics testing company found that 2% of 345 hot dogs tested contained traces of human DNA. However, it was unclear whether that report was a peer-reviewed ...

Chromosomes are tightly coiled structures in each of your cells that contain DNA, the code for all life. DNA is organized in segments on chromosomes called genes. Humans typically have 46 ...

DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are two fundamental molecules in the biology of all living organisms. They play crucial roles in the storage, transmission, and expression of ...

which lets small pieces of primer DNA bind to either side of the region of interest; and elongation, where the enzyme DNA polymerase zips along the single strands starting at the primer to ...
